Sql Sets

Btw, if you need to search for matching sets within a set collection, that is a different problem, and the solutions here may not help much. – Peter Radocchia Sep 7 '10 at 20:01 add a comment . Use set operations us to compare rows from two or more tables. For several classes of problems, is is much easier to use a set operation, than join data.

Watch out, I'm gonna use a Cross Join. Declare @t1 table(val varchar(20)) Declare @t2 table(val varchar(20)) insert into @t1 values ('a') insert into @t1 values ('b') insert into @t1 values ('c') insert into @t1 values ('d') insert into @t2 values ('c') insert into @t2 values ('d') insert into @t2 values ('b') insert into @t2 values ('a') select case when count(1) = (((Select count(1) from @t1) + (Select count(1) from @t2)) / 2.0) then 1 else 0 end as SetsMatch from @t1 t1 cross join @t2 t2 where t1.val = t2.val.

Sql Server Charset

I was trying to find the id of an element that had a set of multi-element child elements that matched a query set of multi-element items. The relevant schema information is: table events, pk id table solutions, pk id, fk event_id ->events table solution_sources, fk solutionid ->solutions columns unitsourceid, alpha Query: find the solution for event with id 110 that has the set of solution_sources that match the set of (unitsourceid, alpha) in ss_tmp.
